I have decided to officially and formally not apologize. I'm not sorry at all, even slightly.

Indeed, I especially want to convey my absence of remorse to anyone who was offended by what I said. If you are the sort of person who gets twisted into knots when someone articulates a point of view that differs from your own, then you are exactly the sort of person who should never receive an apology for a differing point of view â€” if I were offering one, which, again, I'm not.
